Hi John, I also own an AA1, although mine is a bit older than yours (click on
my name next to my comment to see the specs). Mine was originally sold with
XP on it, and it runs Trisquel 8 nicely (running it off the USB as I post
this), so I'm sure it will work fine on yours. Feel free to DM me if you need
any help.
MagicBanana is right that you will need to change the BIOS settings so that
it boots of the USB instead of the internal drive. I suggest you dual-boot at
first (install Trisquel side-by-side with Windows), so you can boot into
Windows to ask for help here, if you run into any problems. Once you are
confident using GNU-Linux, everything is working smoothly (which won't take
long), you can format the Windows partition and replace it with an EXT4
partition to use as a /home drive for your user files.
Welcome to Trisquel!
